Embodiment 1

[0039] see Figure 1-Figure 10 As shown, a high-efficiency needle coke production device includes a coking reaction tower 1, and the output end of the coking reaction tower 1 is connected to a purification tower 9 through a pipeline, which is used for thorough purification and fractionation of high-temperature oil and gas to ensure that it enters the fractionation tower 10 There will be no coke particles inside the high-temperature oil and gas. The purification tower 9 is connected to the fractionation tower 10 through pipelines. The bottom of the coking reaction tower 1 is fixed with a discharge pipe 3. The discharge pipe 3 is equipped with a valve opening and closing device, which can be used to control The opening and closing of the discharge pipe 3, the top of the coking reaction tower 1 is provided with a feed pipe 11, the feed pipe 11 is connected to the fractionation tower 10, and is used to transport the high-temperature oil and gas and the refined coal tar soft pitch m...

Embodiment 2

[0042] see figure 1 , Figure 5-Figure 10 As shown, the end of the gas guide pipe 2 away from the coking reaction tower 1 is fixedly installed with a purification mechanism 5. When the high-temperature oil and gas inside the coking reaction tower 1 are exported, a large amount of coke particles are contained in the escaping high-temperature oil and gas, which is likely to affect the stability of the equipment. The purification mechanism 5 is designed to perform preliminary purification treatment on the escaping high-temperature oil and gas through physical methods, thereby reducing the pressure of the rear transportation pipeline and purification tower 9 for slag removal and fractionation. One side of the purification mechanism 5 is symmetrically arranged with the air guide pipe 2 pipeline, the pipeline is used to connect the purification mechanism 5 and the purification tower 9, the bottom end of the purification mechanism 5 is connected with a return pipe 4, and one end of t...

Embodiment 3

[0044] see figure 1 and Figure 7-Figure 10 As shown, the end of the gas guide pipe 2 away from the coking reaction tower 1 is fixedly installed with a purification mechanism 5. When the high-temperature oil and gas inside the coking reaction tower 1 are exported, a large amount of coke particles are contained in the escaping high-temperature oil and gas, which is likely to affect the stability of the equipment.

Abstract

The invention belongs to the technical field of needle coke production, relates to a high-efficiency needle coke production device and method and aims at solving the problems that coke particles easily block equipment pipelines in the coking process and the temperature is uneven in the coking process. The high-efficiency needle coke production device comprises a coking reaction tower, the output end of the coking reaction tower is connected with a purification tower through a pipeline, a gas guide pipe is arranged on the side wall of the coking reaction tower, and a discharging mechanism is arranged in a discharging pipe; when te high-temperature oil gas circulates in the coking reaction tower, the purification tower and a fractionating tower, the high-temperature oil gas is primarily purified by a purification mechanism every time the high-temperature oil gas is led out of the coking reaction tower, so that the purification pressure of the purification tower is reduced, the high-temperature oil gas in the fractionating tower does not contain scorched particle impurities, and meanwhile, due to the existence of the discharging mechanism, during the internal coking reaction, raw materials move slowly, the temperature uniformity is improved; and the discharging speed is increased through the assistance of the discharging mechanism, and the situation that the discharging pipe is blocked is prevented.

Description

technical field [0001] The invention relates to the technical field of needle coke production, in particular to a high-efficiency needle coke production device and method. Background technique [0002] Needle coke is a high-quality variety that is vigorously developed among carbon materials. Its appearance is a silver-gray porous solid with metallic luster. The needle coke produced can be divided into petroleum series and coal series according to the raw materials used. Raw materials for high-end carbon products such as high-power electrodes, special carbon materials, carbon fibers and their composite materials, especially in the manufacture of high-power and ultra-high-power electrodes, needle coke is the only high-quality material, made of needle coke The advanced graphite electrode has the advantages of strong thermal shock resistance, high mechanical strength, good oxidation performance, low electrode consumption and large allowable current density. [0003] The patent ...
